Title: Fine structure measuring device
Inventor: OIDE TAKAHIRO
IPC: G01B11/06
Filed: 1993-05-26
Abstract: PURPOSE:To enhance measuring accuracy and operability by changing the frequency of a drive signal by adjusting a variable oscillation circuit to change the distance between two beams incident on a fine structure. CONSTITUTION:Two laser beams from an acoustic optical element 12 are allowed to be incident on a beam splitter 15 to be divided into the first luminous flux reflected from the reflecting surface of the beam splitter 5 and the second luminous flux transmitted through the reflecting surface. The first luminous flux is allowed to be incident on a first light detector through a first condensing lens 16 and the first electric signal generated from the light detector 17 is amplified by a first preamplifier 18. The second luminous flux transmitted through a phase shift mask 20 is allowed to be incident on a second light detector 22 through a condensing lens 21 and the second electric signal generated from the second light detector 22 is amplified by a second preamplifier 23. Next, the first and second electric signals are supplied to a phase comparing circuit 24 and the phase difference between both signals is detected and this phase difference signal is outputted to an output terminal 25. The phase difference signal shows the phase difference between the light transmitted through the part provided with a phase shifter of the phase shift mask 20 being an object to be inspected and the light transmitted through the part not provided with the phase shifter of the mask 20.

Title: Sealed type motor-driven compressor
Inventor: FUKUOKA HIROSHI
IPC: F01C21/08
Filed: 1987-05-21
Abstract: PURPOSE:To stabilize the contact between a vane spring and a sealed container by forming a set ring groove which is coaxial with a spring hole and has a large diameter at the edge of the counter partitioning vane side opened port of a spring hole formed in the radial direction of a cylinder. CONSTITUTION:Since a vane spring 13 is fixed by fitting a set ring 15 into a set ring groove 14 formed in a spring hole 9a in the radial direction of a cylinder 6, the surface of the vane spring 13 and the set ring 15 are brought into surface contact. Therefore, the fixation of the vane spring 13 can be stabilized, and deformation can be prevented. Further, since the vane 13 is not constrained in the case when a compression mechanism part 2 is inserted in a sealed container 1, the excessive pushing-in of an vane spring 13 into the spring hole 9a is prevented, and the buckling deformation can be suppressed.

Title: Roll surface machining method
Inventor: UTSUNOMIYA NAOYA
IPC: B23B1/00
Filed: 1987-05-21
Abstract: PURPOSE:To cause the rotation center of a roll to coincide with the axis center of a roll when a roll is heated to a working temperature, by a method wherein non-roundness machining is applied on a roll, supported through a roll shaft box, so that it is formed in roundness at a working temperature. CONSTITUTION:When non-roundness machining is applied on a roll 2 at a non- working temperature so that it is formed in roundness at a working temperature, machining is made on the roll 2 in a manner that the surface of the roller 2 is pressed by means of a press roller device 14 so that a loading zone is formed approximately in the same direction as that prevailing during the use in a state to be supported by shaft boxes 3 and 5. This constitution reduces a condition, influenced by deformation of the roll shaft boxes 3 and 5 and the clearance of a bearing, and enables dissolving of a problem on roll vibration. Concretely, the axial center of the roll 2 is coincided with the actual rotation center of the roll 2 at a working temperature, and roll vibration is prevented from occurring at a given temperature during rolling.

Filed: 1985-06-07
Abstract: PURPOSE:To enable automatic high-precision axial alignment by mounting a semiconductor light-emitting element and a lens base onto the same substrate and preparing the end surface of the semiconductor light-emitting element and a groove fixing a lens through etching. CONSTITUTION:A photo-resist is applied onto a wafer to which the processes of epitaxial growth and the evaporation of an electrode are completed. When the wafer is etched by a HCl+CH3COOH+HPO3 group etching liquid, a vertical surface is obtained in the (011) direction (direction of the arrow A) and a V groove shape is acquired in the (011) direction (direction of the arrow B). Consequently, the end surface of a semiconductor laser 2 and a lens base 3 are obtained through the same etching, and a semiconductor laser is acquired through cleavage at the position of a dotted line. Accordingly, axial alignment requiring high precision is obtained automatically only by loading a lens on the lens base.

Abstract: PURPOSE:To easily and precisely remove a low frequency component included in a reproducing signal by a differentiation operation and to obtain reproducing data with high accuracy from which noise is removed, by generating a gate pulse by using the reproducing signal on which secondary differentiation is applied. CONSTITUTION:A gate pulse generation circuit 40 is constituted of at least a comparator 41 which slices a differentiation signal 30S with a prescribed level and outputs a pulse, and a delay means 42 which outputs the gate pulse by delaying the output pulse of the comparator. In other words, a differentiator 30 functions so as to remove the low frequency component included in the reproducing signal Si, and the comparator 41 in the gate pulse generation circuit 40 generates the pulse by slicing the differentiation signal 30S outputted from the differentiator at the front stage of the circuit with the prescribed level, and functions so as to remove the noise included in the reproducing signal by the pulse. Also, the delay means 42 delays the output pulse of the comparator 41 and outputs the gate pulse, and supplies it to an AND circuit. In such a way, it is possible to make a circuit to remove the low frequency component due to alternate AC coupling unnecessary, and to remove a problem in the AC coupling.

Title: Reflection type sensor for reading mark position with high accuracy
Inventor: NOGUCHI HISAO
IPC: G01B11/00
Filed: 1982-07-19
Abstract: PURPOSE:To read the position of a mark with high accuracy even when a distance or an angle changes, by aranging two convex lenses and a phototube on the axial line of the application of laser beams, by collecting and converging reflected lights from a substance to be detected by said two lens, and by making the converged lights fall on the phototube. CONSTITUTION:Laser beams from a laser generator 31 are applied on a substance 38 to be detected, through the intermediary of a reflection mirror 32 and a total reflection mirror 33. Two convex lenses 34 and 35 and a phototube 36 are arranged coaxially on the axis (a) of application of laser beams. Diffusedly reflected light (b) from a detected mark 39 are turned into parallel lights (c) by the lens 34 and then into convergent lights (d) by the lens 35, and thus reach the phototube 36 without any loss in a quantity of light. Now, when the substance 38 to be detected is inclined a little, the diffusedly reflected lights (b) are also tilted, but no large difference is caused among the reflected lights entering the lens 34, and thus a change in the quantity of light of the phototube 36 is little. This is the same with respect to a change in distance. Therefore, the the position of the mark can be read very accurately even when the distance to the substance to be detected and the angle thereof change.
